Obviously, the drawings in the following description are only some embodiments of the present application. For those of ordinary skill in the art, without creative efforts, other related drawings can be obtained based on these drawings.

[0052] Figure 3 It is a signaling interaction schematic diagram of an FPGA data reconstruction method provided by an embodiment of the present application. Detailed Embodiments

[0053] To make the objectives, technical solutions and advantages of this application more clear and understandable, the following further details this application in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining this application and are not used to limit this application.

[0054] Exemplarily, Figure 1 is a flowchart of a method for FPGA data reconstruction provided by an embodiment of this application. As Figure 1 shown, this method can be applied to the ground side and may include the following steps:

[0055] Step 101: Compress the FPGA original data to obtain compressed data.

[0056] In the embodiment of this application, data compression software can be pre-loaded in the devices on the ground side. Among them, the data compression software can compress the FPGA original data to obtain compressed data. Exemplarily, the GZIP compression algorithm can be used to compress the FPGA original data to obtain compressed data. Using the GZIP compression algorithm to compress the FPGA original data on the ground can reduce the amount of data uploaded to the ground and reduce the time overhead of uploading.

[0057] It should be understood that when selecting an algorithm for compressing the FPGA original data, factors such as compression ratio, compression time, and decompression time need to be considered. However, the embodiment of this application does not limit the specific method for compressing the FPGA original data on the ground side.

[0058] Step 102: Split the compressed data into multiple reconstruction packets according to a preset reconstruction protocol.

[0059] In the embodiment of this application, data splitting software can be pre-loaded in the devices on the ground side, and the compressed file is split into telecommand uplink frames through the data splitting software.

[0060] Optionally, before executing step 102, a preset reconstruction protocol can also be set first. The preset reconstruction protocol includes at least one of data format, packet sequence number, check code, forwarding rate, forwarding port, and forwarding format. Among them, this preset reconstruction protocol is a protocol specifically for on-orbit large-capacity FPGA data reconstruction to ensure the accuracy, scalability, and reliability of telecommand data uploading.

[0061] In this embodiment, a protocol specifically for on-orbit large-capacity FPGA data reconstruction is formulated. This protocol includes contents such as data format, transmission method, and check code. For example, the data format includes parts such as a data header, a data body, and a check code. The data header should include information such as data type, length, and sequence number to facilitate parsing and processing by on-board software. The data body should include the compressed data content, and the check code is used to detect whether errors occur during data transmission.

[0062] Exemplarily, the compressed data is split into multiple reconstructed remote control uplink frames according to a preset reconstruction protocol; the reconstructed remote control uplink frames form a reconstructed packet; wherein, each reconstructed remote control uplink frame adopts a preset format and includes a target identifier. Since each reconstructed frame has a specific format and identifier, it is convenient for management during the transmission and processing processes.

[0063] It should be understood that the size of each reconstructed packet can be reasonably set according to the bandwidth of the satellite communication link and the processing capacity of the on-board software. During the splitting process, it is necessary to ensure that each reconstructed packet contains a complete data block and can be transmitted independently. In addition, a sequence number and check information can be added to each reconstructed packet to facilitate recombination and verification by the on-board software.

[0064] Step 103, upload the reconstructed packet to the satellite side.

[0065] Optionally, the split reconstructed packets are uploaded to the satellite through a ground communication link. During the uploading process (the process of uploading the reconstructed packets to the satellite side), the error sequence number telemetry can be observed in real time. If a transmission error occurs, the reconstructed packet with the error can be retransmitted to ensure the integrity of the data.

[0066] Step 104, receive the packet loss information fed back by the satellite side.

[0067] Correspondingly, an on-board software is generally pre-loaded on the satellite side, and the packet loss information can be fed back based on this on-board software.

[0068] Step 105, perform data reconstruction processing according to the packet loss information to obtain an updated reconstructed packet.

[0069] In the embodiment of the present application, the ground side re-uploads the reconstructed packet according to the packet loss information.

[0070] Step 106, upload the updated reconstructed packet to the satellite side until the satellite side completes the reception and storage of all reconstructed packets.

[0071] In this embodiment, by compressing and splitting the reconstructed packet on the ground, the amount of data transmitted between the ground and the satellite is reduced, the transmission efficiency is improved, and communication resources are saved. In addition, measures such as error checking and packet loss retransmission in the reconstruction protocol ensure the accuracy and reliability of data transmission. After the ground side splits the data into reconstructed packets, the on-board software on the satellite side can process each packet one by one, reducing the difficulty and complexity and improving the processing efficiency.

[0072] It should be emphasized that this embodiment can select appropriate compression algorithms and reconstruction protocols according to different task requirements and data characteristics, and has high flexibility and adaptability.

[0073] Exemplarily, Figure 2The flowchart of another FPGA data reconstruction method provided by the embodiments of this application is as follows. As Figure 2 shown, this method can be applied to the satellite side and may include the following steps:

[0074] Step 201: Receive the reconstruction package uploaded by the ground side.

[0075] In the embodiments of this application, the satellite-side device can pre-load the on-board software and receive the reconstruction package uploaded by the ground side based on this on-board software. Among them, the reconstruction package is obtained by splitting the compressed data corresponding to the FPGA original data by the ground side according to a preset reconstruction protocol. Optionally, the preset reconstruction protocol includes at least one of data format, packet sequence number, check code, forwarding rate, forwarding port, and forwarding format.

[0076] Step 202: Feed back the packet loss information to the ground side.

[0077] In the embodiments of this application, when receiving the reconstruction package, the on-board software can detect the packet loss rate, obtain the packet loss information, and promptly feed back this packet loss information to the ground side.

[0078] Step 203: Receive the updated reconstruction package uploaded by the ground side until all the reconstruction packages are received and stored.

[0079] The ground side will reconstruct the compressed data packet according to the packet loss information fed back by the satellite side to ensure that the satellite side can receive all the reconstruction packages.

[0080] Step 204: Restore the reconstruction package according to the preset reconstruction protocol to obtain the restored FPGA original data.

[0081] Exemplarily, parse all the reconstruction packages according to the preset reconstruction protocol, remove the protocol format, and then restore the compressed data; perform format verification on the compressed data to determine whether the file is in a compressed format; if it is in a compressed format, perform decompression operation to obtain the restored FPGA original data. Among them, during the decompression process, attention should be paid to the integrity of the data.

[0082] Step 205: Send the restored FPGA original data to the user terminal.

[0083] Exemplarily, forward the restored FPGA original data to the user terminal at the rate and port specified by remote control; among them, during the sending process, it should be ensured that the data transmission order is correct. Thus, the on-orbit upgrade of the software is realized.

[0084] In the embodiments of the present application, the satellite side can pre-load the on-board software in advance. The on-board software can completely receive and store the reconstructed telecommand uplink frame, parse the uplink telecommand frame and restore the compressed reconstructed data, and restore the compressed reconstructed data into the original reconstructed data packet. Finally, the on-board software forwards the original reconstructed data packet to the user terminal at the rate and port specified by the telecommand. Thus, efficient and reliable data reconstruction is achieved, breakpoint resume is supported, and the time overhead of reconstruction is significantly reduced. In addition, it also has the advantages of flexibility and strong adaptability, can effectively solve the problem of reconstructing large-capacity FPGA data in space missions, and has important practical application value.

[0085] Exemplarily, Figure 3 is a signaling interaction schematic diagram of an FPGA data reconstruction method provided by an embodiment of the present application, as Figure 3 shown, which may include the following steps:

[0086] Step 301, the ground side compresses the FPGA original data to obtain compressed data.

[0087] Step 302, the ground side splits the compressed data into multiple reconstruction packets according to a preset reconstruction protocol.

[0088] Step 303, the ground side uploads the reconstruction packets to the satellite side.

[0089] Step 304, the satellite side receives the reconstruction packets uploaded by the ground side.

[0090] Step 305, the satellite side feeds back the lost packet information to the ground side.

[0091] Step 306, the ground side performs data reconstruction processing according to the lost packet information to obtain updated reconstruction packets.

[0092] Step 307, the ground side uploads the updated reconstruction packets to the satellite side.

[0093] Step 308, restore the reconstruction packets according to the preset reconstruction protocol to obtain the restored FPGA original data.

[0094] Step 309, send the restored FPGA original data to the user terminal.
